TO ALL WHOM IT MAY CONCERN:

Be it known that we, WAsnIxo'roN STICKNEY end NATHAN 13. Owen, ofLockport, Stateof New York, have invented a. new and useful Compositionfor Fuel; and we hereby declare the following to be a full and exactdescription of the some.

The nature of our invention consists 'in the combination of coal, pitch,coal-tor, benzine, tan-bark, sow-' dust, peat, and other fine woody orvegetable substances, which we truly believe have not been known or usedprior to the invention thereof by your petitioners.

The coal consists of screenings and other fine portions, whichaccumulate in great abundance in cool-yards, and hitherto have beenconsidered comparatively valueless. The tun-bark used (commonly calledspent tanbark) is also comparatively useless and very .obundunt. Those,with other ingredients, hitherto considered of little or no value, areso combined as to form a cheap and convenient fuel, and may becompressed, by mcchan ical power, into blocks convenient for use. Thecoal-tor cements the whole, making a solid mass, which may be readilyignited, e ndis well adapted for common fuel, especially for summer use.

The above ingredients are combined in the following proportions, to wit:Coal, three ports; tan-bark, two (2) parts; saw-dust, two (2) ports;peat, or other fine woody or vegetable matter, one (1) part; cool-tar orpitch, one (1) part, or suflieient to cement the whole or they may becombined in a greater or less proportion of either, securingsubstantially the same result. The whole mass may be easily ignited withshavings or paper, or more readily by the application ofe small quantityof benzine and a match.

Having thus described our invention, what we claim, and desire to secureby Letters Patent of the United States, is

set forth.
